Filed: 1936-02-03
Abstract: 469,617. Coating with metals. SIEMENS BROS. & CO., Ltd., and RIBER, C. R. Feb. 3, 1936, No. 3176. [Class 82 (ii)] A clean metal surface through which articles to be coated by dipping may be immersed and removed is obtained by providing a movable bath for the molten metal and a dross removing member restrained against movement with the bath and adapted to clear the surface of dross as the metal flows past it, for example, by directing the dross below the surface. The dross removing member is preferably secured to a float which covers most of the surface of the metal in the bath. In the form shown, the bath 27, which can be rotated, consists of a casting having an annular groove 28 for the molten metal and a central screw-threaded boss 30 by means of which the bath may be lifted for cleaning &c. A float 33 of refractory material covers most of the surface of the metal, a portion being cut away to provide a free surface for the dipping operation. At one end of the cut-away portion of the float, a dross removing member 34 is provided, shaped as shown in Fig. 5 to direct the dross below the surface of the metal, and the other end of the cut-away portion is shaped to direct the flowing metal below the float. The bath is mounted on a hot plate formed by a metal disc 22 heated by electrical heating elements 21 positioned between the disc 22 and a flanged disc 19, the disc 19 being supported by pillars 20 on a disc 18 which revolves with a hollow shaft through which pass the conductor elements for the hot plate. Above the bath is a T-shaped guide 31 attached to a support 4, the cross-arm of the T being formed with apertures 32 through which pass guide arms 36 on the float 33, so that the float can rise or fall with the level of metal in the bath but cannot follow the flow of the metal. The other arm of the 'T' has a piece stamped out of the middle through which the articles are passed into the bath ; the member 31 acting as a support and a guide for the articles. The coated articles may be knocked on the support to remove excess metal. The coating of the wiring ends of electrical terminals with tin-lead alloy is referred to.

Title: Boron-containing polyesters
Inventor: MUSGRAVE OLIVER CHARLES
IPC: C08G79/08
Filed: 1960-01-29
Abstract: Polyesters are prepared by reacting a diboronic acid or its ester with a polyhydroxy compound or a lower aliphatic ester (e.g. acetate, propionate or butyrate) thereof.  The polyhydroxy compound is a dihydric alcohol having 4 to 11 carbon atoms between the hydroxyl groups, a polyhydric alcohol, or an aromatic compound having two non-adjacent hydroxyl groups.  Examples are: butane 1:4-, pentane 1:5-, hexane 1:6-diols; bis(4 hydroxymethylphenyl)-ether or -methane; glycerol; erythritol; pentitols; hexitols; polyvinyl alcohol. Preferred are compounds having a neopentyl group, e.g. pentaerythritol, trimethylolethane or -propane, tetramethylolcyclopentanone.  The diboronic acid is a polymethylene- or a phenylenediboronic acid, e.g. p-phenylene diboronic acid; tetramethylene diboronic acid, or their tetra-n-butyl esters; penta-, hexa- or decamethylene diboronic acid.  Reactants may be dissolved separately in water or organic solvents (e.g. ethanol, benzene, xylene, acetone), and the heated solutions mixed.  Or the mixed reactants may be heated, with or without solvents as above.  A catalyst, e.g. activated alumina, sodium hydride or p-toluene sulphonic acid may be added.  Any solvent or evolved alcohol or ester is normally distilled off.  Heating is in the range 15 DEG -250 DEG C., preferably 75 DEG -200 DEG C.

Title: Treatment of gases containing titanium dioxide in suspension
Inventor: WALMSLEY ANTHONY
IPC: C01G23/07
Filed: 1958-02-04
Abstract: Gases containing suspended titanium dioxide particles, and particularly those resulting from the vapour phase oxidation of titanium tetrahalides, are cooled by passing the gaseous suspension through a bed of solid particles to form a fluidized bed and simultaneously cooling the fluidized bed so formed with heat transfer surfaces.  The bed is preferably composed of titanium dioxide particles at least 20 times, and preferably at least 100 times, as large as the suspended particles.  The gas velocity of the suspension to be cooled is preferably within the range of 1 1/2 to 3 times the critical fludizing velocity. Heat transfer may be effected by cooled inner walls of the vessel containing the fluidized bed or cooled tubes may be inserted in the bed.  Stagewise cooling through a plurality of fluidized beds may be employed, the average particle size, or preferably the horizontal cross-sectional area of the beds, decreasing in sequential beds in the direction of flow of the cooled suspension. The invention is particularly applicable to the cooling of gas resulting from the oxidation of titanium tetrahalides (other than the tetrafluoride) at a temperature of at least 800 DEG C. in the presence of a fluidized bed of titanium dioxide particles.  Such particles are preferably also employed in the subsequent fluidized beds which serve to cool the suspension from the reactor, and it is then desirable that the critical fluidizing velocity of the particles in the cooling bed be substantially equal to the critical fluidizing velocity of those in the reaction bed and the sieve analysis of the particles of both beds is preferably substantially the same.  To this end the particle size of the reaction bed is preferably controlled as in Specification 866,363. According to an example, the titanium dioxide was produced by oxidation of titanium tetrachloride in a fluidized bed of titanium dioxide particle of 14 to 36 mesh B.S.S. size.  The reaction was effected at 1,040 DEG C. in the presence of carbon monoxide which was burnt to counteract heat losses. 60% of the titanium dioxide produced was retained on the bed as a coating on the particles and the remainder in suspension had a mean particle size of 0,86 microns.  The effluent suspension from the reaction bed was passed into a water-jacketed aluminium tube containing a bed of titanium dioxide particles.  The temperature of the effluent gas from this cooling bed was 226 DEG C.
